Well sweetie, that bright star in the eastern sky in the northern hemisphere? That's the North Star, also known as Polaris. It's been a guiding light for sailors and travelers for centuries because it stays relatively fixed in the sky while other stars appear to move throughout the night. So if you ever find yourself lost, just look up at Polaris and follow that sucker north.
There is no time when the complete northern hemisphere is dark. As the earth rotates there is always some part of the northern hemisphere facing the sun, so it is bright there, and there is always a part of it that is facing away from the sun, so it is dark there.
Lyra contains the third brightest star in the northern hemisphere, Vega. From spring to autumn, it is clearly visible, while during the winter months, it is visible low on the northern horizon.
Betelgeuse is in the constellation Orion and is best seen during the winter months in the northern hemisphere. It is very well placed for viewing around the months of November, December and January. Orion is a very easy constellation to find and Betelgeuse is the very bright and reddish looking star at the top left of it.
Yes, the Andromeda galaxy is visible from Earth with the naked eye under ideal conditions. It is the closest spiral galaxy to our Milky Way and can be seen in the night sky from the Northern Hemisphere.
That would be Jupiter - which technically isn't a star, but a planet. However, it looks just like a star. Also, since it is near the Ecliptic, it can be seen both in the northern and southern hemisphere. (Answered in January 2012 - at other times, the answer will vary - other bright stars or planets may appear.)
the world is upsidedown. A2. Well, the world is right way up, it is the sky (and stars) that are inverted. When the left half of the moon is bright as seen in the northern hemisphere, in the southern hemisphere it will be the right half that is bright
That is Jupiter, very bright and high up in the northern hemisphere around midnight just now.
Yes, Sirius is a bright star and is visible in the northern hemisphere during the summer months. It is one of the brightest stars in the night sky and can be seen low on the horizon in the southeast during the summer evenings.

We won't know the answer to that question until we know that we have discovered all of the stars above the horizon in the northern hemisphere, and measured the brightness of each one. In fact, now that we ponder the question some more, it's obvious that the question can never be answered. The least bright star can't be detected, even by the most powerful telescope, so we're not even aware that it exists.
Polaris, the North Star, is located near the North Celestial Pole which is visible only from the Northern Hemisphere. In the Southern Hemisphere, there is no bright star close to the South Celestial Pole like Polaris because the South Celestial Pole does not have a similarly positioned bright star. Therefore, observers in the Southern Hemisphere cannot see Polaris due to its location in the sky.
You can find the Big Dipper in the northern sky, all year round in the Northern Hemisphere. It is a part of the Ursa Major constellation and is easily identifiable by its spoon-like shape of seven bright stars.
Yes. If you live in the northern hemisphere it has been visible for many months now, looking like a bright star towards the south.
